About vertical.solar and Over Easy Solar
Started by Over Easy Solar in January 2022, vertical.solar was originally a research project started to develop data and knowledge necessary for the first commercial vertical solar rooftop product in the world: the lightweight, vertically mounted bifacial VPV unit.

Through the project, we have developed leading knowledge about vertical bifacial solar installations, ranging from solar panel design, mounting structure design, energy yield simulations and wind simulations, to testing and certification. We partner up with leading research partners in the field of PV: Institute for Energy Technology, Fraunhofer ISE and others.
Milestones

Wind tunnel tests and analysis done
Computational fluid dynamics simulations performed
Energy yield results presented at the Norwegian Solar Cell Conference in Son, Norway
First LCA analysis done on VPV system
Hail testing and simulation of mechanical strain from wind load on mounting structure
Modeling and energy yield results presented
Own energy yield simulation model for VPV installations launched
